Reaction Conditions

Reaction Steps

Into a flask, 10.00 g of 3,6-dibromo-9H-carbazole, 4.1 ml of 1-fluoronaphthalene, 12.06 g of cesium carbonate, and 300 ml of dimethylsulfoxide were put, and the solution was stirred at 145° C. for 36 hours under nitrogen atmosphere. After heating, the reaction liquid was cooled to room temperature and then filtrated, and the filtrates were concentrated by a vacuum pump. The concentrates were purified by silica gel column chromatography, and then washed by methanol, and thus 5.5 g of 3,6-dibromo-9-naphthalene-1-yl-carbazole was obtained.
